BAG-HOLDING DEVICE.

Specification of Letters Patent.

Application led Febriiary 19, 1914. Serial No. 819,638.

To all 'whom t may concern Be it known that I, ARTHUR D. MoIi-rnnson, a citizen of the United States residing at Oak Park, in the county of look and Sta-te of Illinois7 have invented certain new and useful Improvements in Bag-Holding Devices, of which the following is a specification.

My invention relates to devices for hold- `ing fabric bags open for conveniently filling, and for subsequently releasing the bags.

One of the objects of my invention is to provide a means, for association with a usual filling spout, forfirmly and securely holding a bag open, around the mouth of the spout, so that it cannot become unintentionally disengaged, and whereby the bag may be readily released, by the proper manipulation of the device, without the necessity of first lifting the bag and contents off of each supporting spur, or hook, in an effort to remove 1t, after being filled.

Another object of my invention is to provide a self contained device, of uniform size and best adapted to the standard bag, wherein the parts are properly assembled and relatively disposed and which may, bodily, be attached to filling spouts of varying sizes and dimension and which consequently may be sold as a unitary attachment, ready for convenient and immediate application when received by the purchaser.

Other and further objects of my invention will become readily apparent to persons skilled in the art from a consideration of the following description when taken in conjunction with the drawing wherein- Figure 1 is an elevation of a usual filling spout7 showing my device attached thereto. Fig. 2 is a view of one of the sides, at 90 vdegrees from the side shown in Fig. 1 and Fig. 3 is a transverse section taken on line 3 3 0f Fig. 1.

In all the views the same reference characters are employed to indicate similar parts. e is the ordinary flour or grain conveying fllingspout as used in flour, grain or feed mills, or the like, through which such commodities as grain, bran, flour er meal may be passed when it is desired to deposit such materials into bags. The superposed hopper 6, may be located at a remote peint from the lower end of the spout 5. The spout 5 termintes, at its lower end, as shown in dotted lines, as at 7. Such spouts are usually rec` tangular in shape and are frequentlyof size well adapted to fit into the mouth of the standard bag, but sometimes they are made smaller' than thebag and for this reason, owing to the irregularity 4in the varying sizes of the spouts, it will be difficult for a purchaser of one of my bag filling devices to properly dispose the various parts in their coperative relation upon spouts, of such various dimensions. Therefore I mount the parts of my device on a spout section in the shop in which the device is made, and ship it as a lcomplete entity to be bodily attached` to the spout, by blocking in around such spout that may be made of unusually small dimensions. i In carrying my inventlon into effect I provide a sheet metal spout section, 10 preferably of rectangular form and of size best adapted for the standard bag. It is intended to lit around and to contain the lower end of spout 5 through which the cereals, or other comnlinuted material is to pass into the bag.

When the spout 5 is smaller than the inte` rior of the section l0, its outside dimensions may be increased by nailing on to the spout pieces of wood of' suitable thickness to fill in the space between the outside dimensions of the spout and the inside surface of the section 10. After lthis has been done holding as by a bolt 16, which passes through the wall of the section and through the wall of" the disk, and of the handle, the parts being Patented Nov. 24,1914."

secured on the bolt 16 by means of a nut 17 or any other suitable manner that may be adapted for the purpose. The handle 18 is offset, as at 13', to permit the passage of a link 18, between the disk and the handle. The disk 12 may be rotated by the handle upon the axis 16. The link 18 is downturned, as at 19, and is pivoted to the disk, as at 20. The other end is downturned, as at 21, and is pivoted to a crank arm 22 of shaft 2a, as at 2 3. A similar link 18 is upturned, as at 19, and is pivoted to the disk 12, as at 20. lts other end 21 is also upturned, and is pivoted to a ,crank arm 22, of the shaft 24 as at 23.

On opposite sides, of the section 10, and at substantial right angles to the side thereof on which is contained the handle 13, and the mechanism just described, is a rotatable shaft 24. Thecrank arms 22 and 22 are secured to the shafts 2li-24; and by means of which the shafts 2K1, 24 may be oscillated by `movement of the links 18-18 when the handle 13 is rotated substantially one-half of a. revolution, as shown in dotted lines in Fig. 1.

Projecting from the sides of the shafts 241-24 are bag engaging spurs 26-26, there being two or more on each of the shafts 241:. YVhen the parts are in the posi'- tion shown in full lines in Fig. 1, the spurs 26 are pointing upwardly, their axes being abouti/l0 degrees from a vertical plane, and in such positions `as to firmly retain and hold the bag when it is threaded over the spurs. f Vhen the device is to be used, for holdingand supporting a bag in place, the parts are inthe positions shown in full lines in Fig. 1 with the handle in a vertical plane and pointing upwardly. 1t will be noticed that any strain coming on the spurs 26-26, due to the weight of the bag and contents, tending to rotate the shafts 24-24 is impressed upon the ,crank arms y22--22 that are connected to the links 18-18 and that the pivotal points 28-23 joining the links 18-18 with the crank arms 22 22 of the respective links are located diametrically on opposite sides of the axis of the disk 12 so that anypulling strain on either of the outer ends `of lthe links 18 or 18 will come directly through the axis 16 of the rotating parts and thereby the kparts are accurately held and Vfirmly locked in position against accidental `or unintentional movement to release the'bag ,To Yrelease `the'bag, the handle 13 is rotated upon the axis 16 to the right until it again occupies a vertical plane, with the handlepointing downwardly, at whi'ch time the'linksj18-18 are placed in the positions shown in dotted lines, wherein the crank arms are at substantial right angles to their normal locked positions and the spurs,

26-26, are turned downwardly so that the bag will readily slip therefrom.

lo return the parts to the positions shown in full lines, in Fig. 17 it is only necessary to rotate the handle 18 half a revolution, back to the original position, at which time the lower surface of the handle 18, as at 13a will act as astop to prevent further movement of the handle, by its contact with the link 18 and a similar surface of the handle, on the opposite side of its'aXis, operates as a stop to the link 18 so that the handle 13 may not be rotated to the left substantially farther' than the position shown in Fig. 1.

The general practice of the prior art was todrive sharp pointed nails, or spurs, into the sides of the spout 5 in positions substantially corresponding with those occupied by the rotatable spurs 26-26, of my device, and to thread the bag upon these four or more stationary spurs to hold it in place, and after the bag had been filled it was necessary to lift the entire contents of the bag four or more times before it lcould be en tirely released from the yengaging devices. The labor thus entailed upon the operator was very wearying and unnecessary and re quired the services of a robust, strong attendant to be able to stand the imposed burden. My device maybe readily operated by a child as the weight of the filled bag tends to assist in the operation of its release when the handle is intentionally turned for this purpose.

lVhile l have herein shown a single embodiment of my invention for purpose of complete disclosure it is manifest that changes may be made therein within the scope of the claims without departure from the spirit of the invention.

Having described my invention, `what I claim is 1 A bag holding device comprising a rectangular spout section, adapted for connection to a material delivery spout; two shafts, one on each side thereof; bearings, for the shafts carried by the walls of the spout section, said bearings having arcuate slots therein; spurs carried by the shafts and extending through the arcuate slots, and means to oscillate said shafts to move the spurs to bag holding and bag releasingposition.

2. A device of the character described, comprising a rectangular spout engaging section, 'having means for connecting to a spout; rotatable shafts, one on each opposite side of the lower end of said section; bag engaging spurs projecting laterally from said shafts; a crank arm on each said shaft projecting in front of an intermediate side of said section; a dished disk pivotally connected at its center to said spout with its conveXed side adjacent the wall of the spout, a pair of links connecting said ranic arms with said disk et diametrcally hand inthe presence of two subscribing Witopposite points near its periphery und a nesses.
